Rachel Green is Monica's best friend from high school and therefore a key member of the group of Friends. Rachel stars off as a waitress at the Central Perk where the gang hangs out, but later becomes a buyer at Bloomingdale's.
Rachel dates Ross on and off throughout the series and the two eventually have a baby girl, Emma, at the end of season eight.
Rachel: Do you think it's easy for me to see you with somebody else?
Ross: You know what, hey! You're the one who ended it! Remember?
Rachel: Yeah, because I was mad at you! Not because I stopped loving you!
Rachel: Daddy! Daddy listen to me! It's like all my life everyone's told me, "You're a shoe! You're a shoe! You're a shoe!" Well, what if I don't want to be a shoe? What if I wanna be a purse or a hat? No I don't want you to buy me a hat, I'm saying I am a hat. It's a metaphor Daddy!
Ross: You can see where he'd have trouble.
